[PATCH] D102782: Add support for Warning Flag "-Wstack-usage="

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

In GCC -Wstack-usage= is more powerful. It can check `warning: stack usage might be unbounded`.

If this is currently just an alias, does it address some application pain? If we don't actually implement the -Wstack-usage= functionality, I'd hope that applications know this and gracefully degrade to -Wframe-larger-than= instead.
Having this functionality could give false impression that we have implemented the powerful detection usage.
And I expect that -Wstack-usage= is rarely used.
